But occasionally cosmic rays have much higher energy than usual. We've known about this since 1962, but we still have no idea why. We also don't know where this ultra-high-energy cosmic radiation ...

An ultra-high-energy cosmic ray carries tens of millions of times more energy than any human-made particle accelerator such as the Large Hadron Collider, the most powerful accelerator ever built ...

Historically, other high-energy cosmic rays have been detected, such as a 320-EeV particle in 1991, a 213-EeV particle in 1993, and a 280-EeV particle in 2001, all in the Northern Hemisphere.

A groundbreaking new survey from China’s LHAASO observatory has unveiled powerful ultrahigh-energy gamma-ray emissions across ...

This energy level matches the most energetic cosmic ray ever observed, nicknamed the “Oh-My-God particle”, which was estimated to have an energy of 320 EeV when detected in 1991. From many candidates, ...

LHAASO has discovered a giant ultra-high-energy gamma-ray bubble structure in the Cygnus star-forming region, ... These high-energy cosmic rays collide with interstellar gas and produce gamma rays.

Researchers recently detected an "ultra-high-energy" cosmic ray, which is the most powerful since the famous "Oh My God" particle was detected in 1991. They have no idea where it came from.

Cosmic rays are made of subatomic particles, such as protons and electrons, whose energies span a wide spectrum. Ultra-high-energy cosmic rays easily host tens of millions of times more energy ...
